Problems solved by technology

However, after the red willows were stubbled in these places, a large number of red willow stalks were piled up in the fields or burned, affecting the appearance of the village and polluting the environment. It is a pity to discard them.

specific Embodiment approach

[0019] The preferred embodiment of the movable red willow stalk aggregation sand barrier of the present invention is:

[0020] A plurality of tamarisk poles are bundled into aggregated bundles, and multiple bundles of aggregated bundles are combined into a movable aggregated red willow pole sand barrier.

[0021] The cross-section of the polymer bundle is any one or more of the following: circular, pentagonal, rectangular, trapezoidal, rhombus, triangle;

[0022] The aggregate bundle has a height of 8-10 cm and a length of 50-100 cm.

[0023] Multiple bundles of aggregated bundles are combined into grid-shaped sand barriers of 50cm×50cm, 50cm×1m, 1m×1m, 1m×2m or 2m×2m, or combined into row-type sand barriers, or combined into belt-shaped sand barriers Barriers, or combined into fishbone-shaped sand barriers.

[0024] The movable red willow stalk aggregated sand barrier patented by the present invention uses a large number of red willow stalks piled up to make the cross secti...

specific Embodiment

[0037] Such as Figure 1 to Figure 9 As shown, first collect the red willow stalks, remove the branches, and leave the main branches.

[0038] Such as figure 1 As shown, butt the red willow stalks with each other, and weave a circular (or circular, pentagonal, rectangular, trapezoidal, rhombus and triangular corner) aggregate sand barrier with a length of 100cm and a cross-sectional diameter of 8-10cm. Finally, repair the residual forks at both ends neatly. The above-mentioned movable red willow pole aggregation sand barrier can be arranged on the surface of the dune according to the following setting method to achieve the effect of windbreak and sand fixation:

[0039] Step 1: Place the movable red willow pole aggregation sand barrier directly on the surface of the dune, and compact the sand barrier so that it is in full contact with the sand surface without leaving any gaps;

[0040] Step 2: Set the movable red willow pole aggregation sand barrier into a grid shape or oth...

Abstract

The invention discloses a movable sand-protecting barrier composed of gathered rose willow bars; a plurality of rose willow bars are into gathered bundles, and a plurality of gathered bundles randomly form a grid-like sand-protecting barrier, a line type sand-protecting barrier or a fishbone-shaped sand-protecting barrier with the specification of 50*50 cm, 50 cm*1 m, 1*1 m, 1*2 m or 2*2 m in a moving dune, a semi-mobile dune and a fixed dune; then the sand-protecting barrier can be laid contiguously in a large area. The movable sand-protecting barrier composed of gathered rose willow bars is 8-10 cm in height and 50-100 cm in length; the cross section of the movable sand-protecting barrier can be round, pentagonal, rectangular, trapezoidal, rhombic or triangular. The movable sand-protecting barrier is time-saving, labor-saving, convenient, flexible and rapid when being built, the structure is stable and simple, and the used material is low in cost; the movable sand-protecting barrier is strong in weather resistance and corrosion resistance and has the good effects of wind prevention, sand fixation and ecological disaster reduction.

Description

technical field [0001] The invention relates to an obstacle for windbreak and sand fixation and ecological sand control, in particular to a movable sand barrier made of red willow stalks. Background technique [0002] Northeast Asia is currently one of the most severely affected areas in the world by sandstorms. Due to the impact of global climate change and human activities, about 1 / 3 of the world's land area is threatened by desertification. In the arid grasslands and desertified areas of northern China, land desertification is increasingly expanding, and the frequency, intensity, and scope of influence of regional sandstorms are increasing and expanding. The occurrence of sandstorms not only directly leads to strong wind erosion on the surface of the dust source area, aggravating the desertification process of the land, but also causes heavy economic losses to the industrial and agricultural production of downstream areas and countries, and even has a serious impact on r...
